Maleic anhydride

Maleic anhydride is an intermediate product in the chemical industry. Maleic anhydride refers to the anhydride of maleic acid, which in turn belongs to the group of unsaturated di-carbon acids. In the production process, the white, water-soluble crystals are derived from the partial oxidation of n-butene.


As an industrial intermediate product, it is widely used in the manufacture of unsaturated polyesters and in the synthesis of tensides, insecticides, herbicides, fungicides, growth regulators (e.g. maleic anhydride), as well as in other chemical compounds, such as 1,4-butanediol, which is used in the production of polyurethane and elastanes, or co-polymers, which are an important lubricant.
